DETACHAB LE BUTTON.

SPECIFICATION forming part of Letters Patent No. 299,099, dated May 27, 188-11.

Application filed February 1, 1884. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN J. ANGELL, of Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Detachable Buttons; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming apart of the same, to be a description thereof.

This invent-ion consists in a detachable button having a hollow stem rigidly secured to the button-head, a T-shape member having cam-surfaces formed on its shank portion, and mounted to revolve axially in said hollowstem and with relation to the button-head, and springs located within and inclosed by the stem and engaging the shank of the T-shape member to hold the head thereof in position.

It also consists in providing the inner end of the T-shape member with a shoulder,and in arranging the springs to engage said shoulder, and thereby retain said member in the stem, as will hereinafter appear.

Referring to the drawings, Figure 1 represents a side view of the button with the head of the T-shape member in position to allow the button to be applied. Fig. 2 shows the same with the head of the T-shape member in position to retain the button in place. Figs. 3 and 4. represent rear views of the button, with the head of the T-shape member in the positions shown in Figs. 1 and 2, respectively. Fig. -5 represents avertical section of the but ton,with the T-shape member in the position shown in Fig. 2. Fig. Gshows a transverse section on line or m of Fig. 5. Fig. 7 shows the T-shape member in perspective.

A is the button-head, which may be of any preferred style or construction. To the back of this head a hollow stem, B, is rigidly secured by solder or other means. As shown in Fig. 4., the stem B is oblong in plan, and has its free end 6 closed. The end I) is perforated to form a bearing for the cylindrical portion 0 of the shank c of the T-shape member 0, which is mounted to revolve axially in said stem and with relation to the button-head. Located within the stem B are two U shape springs, D, the inner arms, (I, of which engage the shank of the member 0, and the outer arms,

(2, of which bear against thewalls of thestem,

as shown in Fig. 6. In order that the head 0 of the member 0 maybe retained in aposition to hold the button in place, and also in order that it may be retained in a position to allow the button to be applied, the shank c is .furnished with cam-surfaces or flattened portions 8 s and s s, as shown in Figs. 6 and 7, against which the inner arms, d, of the springs bear, the said arms engaging the surfaces 8 s when the head 0 of the member 0 is in the position shown in Figs. 2 and 4, and engaging the surfaces s s when said head 0 is in the position shown in Figs. 1 and 3. If desired, however, the fiat surfaces s 8 may be dispensed with.

As shown in Figs. 5 and 7, the inner end of the shank c is provided with a shoulder, 0 and, as shown in Fig. 5, the ends of the arms (1 of the springs D take bearing against said shoulder, the ends of the arm d bear against the back-plate of the button-head, and the central portions or bends of said springs bear upon the end 6 of the stem B. By this arrangement the member 0 is held in the stem and is free to be turned axially with relation to the button-head. The member 0 may be held in the stem B, however, by springs D of other forms than U shape-as, for instance, by springs of a) form, as will be readily understood. I

In assembling the parts of the button, the

- shank of the member 0 is passed through the perforation in the end I) of the stem B, the springs are forced into their positions within the stem, so that their inner ends are under the shoulder 0 and the stem is soldered or otherwise rigidly secured to the button-head. Preferably, the inner end of the stem is provided with flanges b, as shown in Figs. 3 and 4, to afford a broader surface for soldering the stem to the button-head.

Although I prefer to retain the member 0 in the stem B by causing the inner ends of the springs D to engage a shoulder, c, on the shank of said member, yet the member may be retained in the stem, so as to revolve therein shoulder 0 and soldered to the innerwalls of I00 2. The combination of the stem 13, the T- 15' shape member 0, having cam-surfaces upon its shank portiomas described, and provided with a shoulder, 0 and springs D, which engage the shank of the stem and the shoulder thereon and hold the T-shape member ,in the 20 stem, substantially as set forth.
